Basic Solar Panel Question
I am full time and met another full-timer who has a solar Panel issue. He is in an older C-Class Ford and picked up a panel and got it twisted. Apparently, he reversed the polarity and tried to hook...

It looks to me like that is the J-box that is on the back of every solar panel, and it has 2 wires coming from it, Probably negative on the left, Positive on the right. (is that the one with the + tag on it?)
If that's the case, you won't see any wires from this box to the panel, since they will come through the back of the panel from the cells into the box.
So, put your DVM into the 100V DC range, and put the black lead on the left wire (in the J-box) and the red lead on the Right Wire in the box, and you should see voltage, somewhere around 40-50V.
if the meter reads 1, with no tenths etc, that usually means out of range. Even with the leads touching nothing, your meter should read 0.00 or so.
If all else fails, maybe try a different meter?
Good luck.
